Yup. I set my troops to 999 cap. But if you want the red/green/blue bar to show more than 100, you've gotta edit a few LUA scripts.
Inside of gameconfig.xml
Look for <soldierDevelopment>Then underneath, set all the globalMaxProgress= to whatever you want your cap to be. For me, i set it to globalMaxProgress=999
To edit the bars to show more than 100, you'll need to edit sequipview.lua. I believe the bars in combat already scale, so you really just need to edit the bars for the base's equip screen.
The fastest way to find the values is to search for max = 100, but you can also search for:

Have fun!
