Excalibur flat panel

Hey guys, can anyone help me out to set up the flats sequence with this panel?
I can connect and all, but i find it hard how do i set up brightness level for each filter?

Meaning i want to find out what brightness level and exposure time i need for each filter and use same setting for next run.
When using Sequence, i can choose flats, but i cannot set the brightness needed for specific filter.
Does auto flat is the only one option?

The sequence is not the right place where to do automate flat.

Please use the AutoFlat feature from onthefly or from DragScript:

All the best
