Not sure. They probably remove some actions for some reason.

Trying to get this to work on Exile, works fine on base A3 but would love to get the same scroll options in Exile for it to work.

Think this is a thing of CfgRemoteExec classes. You have to add it in CfgRemoteExec.hpp.
Example:
For the "rappel from helicopter" mod you must add .....

class AR_Client_Rappel_From_Heli { allowedTargets=0; };
class AR_Hint { allowedTargets=1; };
class AR_Hide_Object_Global { allowedTargets=2; };
class AR_Enable_Rappelling_Animation { allowedTargets=2; };
class AR_Rappel_From_Heli { allowedTargets=2; };

So it´s part of the developer to give us the classes.
