Right hand Fire while in Freeclimb?

[astralflux]

As the title suggests, is there a way to enable shooter fire smg/pistol from right hand while in freeclimb?

Scenario; Player is hanging onto the side of a moving train, needs to shoot while hanging on to moving train.

Need advice/assistance on how to make this work. Thank you!!!

p.s I did search the forum but didn't find anything related to this.

The FreeClimb add-on does not support shooter atm, this would require a lot of custom coding and custom animations
