Thanks for the great suggestion, Mike.
As I presume you’re aware (having posted this in the feature request section), you cannot currently have a trigger based on a number of hours of usage, but this is a great idea. You can, of course, have triggers based on the number of uses.
I’m sure we can look at adding support for triggering C&M records based a number of hours of usage of the equipment. I’d suggest giving your own thread a vote (they’re a key factor in our prioritisation process) and if anyone else would like to see this, please also give this thread a vote
