Perfect timing to do this mod...
In my case I used regular rubber hose clamps instead of the one-time use shown in the photo.
This makes it easier to screw the cap on the brake canister and then connect to the Motive bleeder unit. Also great if you have different adapters (I use mine to help a few friends with GM cars).
To replace the hoses I just went to the local Lowes or Home Depot and got some reinforced oil resistance clear hose... unit has been working like a champ. And yes, I like it wet...

+1... I don't store the fluid in the canister... and the unit gets cleaned after each use... So far I have been good at guessing how much fluid to put in the canister. If there is anything left unused in the canister I discard it.

I have always wondered why people risk flooding air into the system, having to check and fill and check and fill depressurising and repressurising each time. I like to spend my time and effort on a good flush and inspecting the system as the fluid runs out not looking at and topping the fluid level 10 times. Another nice thing about using it wet is you add fluid into the tank while away from the car not leaning over and pouring inside the car.

Flushing exact quantities thru the system is easy to determine by marking the side of the reservoir jug and catch jug with a black marker. I used to bleed with a dry reservoir jug in order to avoid pressure leak mishap at the Motive jug. Now I fill reservoir jug with a liter and use a 10 foot long vinyl tube to reduce possibility of paint damage. I clean out mine with rubbing alcohol.
Motive's simple design is ok. But poorly manufactured with extremely cheap components.

Via testing I found that the fluid in reservoir had the highest moisture content. Pushing this fluid closer to the heated portions of the system might be counter productive. For a track car this is moot as the fluid is likley close to the dry boil point throughout but in older fluid a partial bleed might only put more water in the heated areas.

Resurrecting this thread. I was bleeding brakes this morning and the tubing kept cracking. I replaced both ends twice to get me through the procedure. I'll get some of the vinyl tubing locally and will do the pictured mod in the quote below. Using the air line plug and coupler is a great idea for a bleeder without the swivel cap. Thanks for posting this!
