I'm not very savvy on computers and gaming constructs so it is hard for me to make certain changes that require multi-mode options. For example, how do I convert the CA (actually a PS) Deutchland to dual main battery and secondary battery modes like the BB Deutchland and BC Scharnhorst? All of these class ships had 11"/280mm main batteries: BB 2X2; CA 2X3; and BC 3X3. Also, self propelled artillery like the Wespe and Hummel) should not be able to move AND shoot at max
(indirect fire) range: however, they could move and shoot at 2 hex range by using their own crews to target observed enemy/hexes. Assault artillery like the StuG/Hs and (I)SUs, Lee M3, Char B1, etc, should (like heavy infantry with mortar fire)
when firing at 2 or less range as artillery be able to INSTANTLY revert back to their anti=tank mode.

Actually it would work exactly like with the BBs. Use it as template in the units.csv file.
Basically you have to create a new unit with the desired stats and then use the "switch" column to point to this new configuration.

To prohibit move and shoot, you can add "staticfire" to the traits column.

Again, would work as the heavy inf. units setup, use that as template. The "instantRevert" switch does exactly that.
But if the unit's set to artillery mode and then fires the mortar, I'm not sure whether an instant revert to the AT setting's possible. I guess it would just revert back to the arty setting. Good luck!
