Sure! If you look at madman's bestiaries made for the Pathfinder community located here:

For example, if you load the first bestiary module and open the Demon, Glabrezu NPC, you will see in its spell-like abilities all the (At will), (Constant), (1/day), (1/month) tags in front of the spell names.
This goes for all of the NPC with spell-like abilities in his modules. They are sorted by usage instead of by spell level, but when I use this resource, I manually replace all the spells at the correct spell level while keeping the duration tag in front.
