Steam Controller Action Sets

[KerbinDallas]

I'm trying to set up a configuration for KSP on the Steam Controller and I'm having trouble adding new action sets to the default setup. There seems to be no option to add action set like other games and also when selecting 'set' within legacy controls I don't get a popup like normal. I could potentially set up a new scheme from scratch but I want to use some of the triggers that the default config uses such as changing to map mode, flight mode, VAB etc.

The main reason for doing this is to adjust the 'Docking Controls' mode because the default bindings use the space bar to switch between translation and rotation however this can be achieved with the two thumb pads on the controller at the same time. The problem is that docking controls in game remove the ability to use translation and rotation at the same time, unlike flight control with the 'i, j, k, l, h, n' keys. Another solution I was considering was editing the config for the docking mode key bindings in 'settings.cfg' in the main KSP directory and adding the keys back in but so far I haven't figured out how to do that.

Any help would be appreciated, Thank you.

Edit: After experimenting more it doesn't seem possible to delete existing action sets at all from the configuration screen. I have tested this in both 1.0.5 and 1.1 pre.
