How to include Join function in conversation?

[rebelrunner 10]

I am new to the ArmA editor, and am trying to create a custom mission in which the player can recruit encountered allies. How would I go about implementing this, if it is possible? I would like something like a selectable option in the standard conversation interaction, that the player can click to place the soldier under the command. In effect, acting like a Join-type waypoint.

UPDATE: I went ahead and figured out some scripting, and crafted a solution that mostly relies on the addAction and Join commands. Seems to work pretty well thus far.
