What would your feature do ?

After purchasing the 5080, I ran into the problem of not being able to run my version of webUi. After searching the discussions, I found a working version for my configuration and successfully launched it. However, now I can't change the architecture, being able to use only sd (switching to flux or xl from the previous version doesn't work, because the switchover switch is missing in the UI)

My build is

Proposed workflow

1. Install last version from Nvidia Blackwell 50XX GPU instructions (Windows) #16818
2. Launh app
3. No tool to change the architecture
