Link Special Ability Uses

Would it be possible to link the Uses for special abilities, so that multiple programmed abilities use the same per day usage pool?

This would be helpful with channeling. As there are several ways to use your channel, and they all go off your single per day pool. Currently, you have to program in each one, then manually track how many you have left by doing math for each one. For example, my Versatile Channeler Cleric, I have to program in four different channels. Positive energy vs living, Positive energy vs undead, Negative energy vs living, Negative energy vs undead. Since he can channel 7 times a day, I have to keep track of each one and count how many I've used. If they could all be linked to a single pool, well, that would just be so much easier.
