Has anyone been able to create caladdminutes function? Been searching in availab

caladdhours is not accepting decimal values so it won't work in our scenario. let's say we need to add 1.5 hrs it will round off automatically, so we are looking for ways to use the same function as caladdhours (which calculates based on business hours) but input will be minutes (this is to solve the issue of 1.5hrs converting to 2hrs and make it 90minutes instead). We are using this for escalation.
