Changes are being made to the bot will support this in the near future.
Right now, that logic is only run from CRs, which only get executed in combat. The only other way to cast the spell again, would be to do it in a plugin, but normal bot logic might interfere with that.
The current plan is to have a sort of "post combat" logic users can modify to handle things like waiting for ES/health regen, cooldowns, cancelling buffs like AA, and other things of that nature.
