presets to reward / lose multiple currencies

Is there a way to have a preset where we can list all gold/xp bonuses, and possibly have some rewards that give both?

Ex: I have student reading goals and I want to give them 100 gp if their goal is met, but I also want to give them xp.  right now I have to click both xp and gold to use the presets, or I have to use the +/- and type in the reason. 

Is there a way to put in presets for the +/- button like the others, or some other option?  Am I missing it somewhere?

Thanks!
