Different service time for different employee

Hi,

I'd like to request adding a feature to the Custom Duration & Pricing addon. It would be awesome if we could have one service that could have different time/rate for a different employee ie. when you have stuff levels like junior, senior, instructor etc.

Junior could have different time of service ie. 60 mins instead of the 45mins for the senior/instructor or different price.

So one service - let's call it a massage:
Junior - 60 mins
Senior - 45 mins

Currently you need to create multiple services to have different time settings per different employee

Thank you!
