Resource Management issue

[KristenM]

Now that you have implemented the Resource option, I am using it. But it's not as functional as I hoped. 

I have a service that requires 2 resources, I can select 2 resources but it only blocks one of them. The problem is that those 2 resources can be used individually as add ons in other services. So when they book the one service that requires both I need both resources blocked so one of the resources can't get double booked.

I just upgraded my account to use the resources option. The problem is that I can select 2 resources for a service but it will only block one of the selected resources for a service. 
I have a service that requires 2 resources and I have other services and add ons that require only one or the other of the resources. I don't want to limit my bookings by putting both resources as one nor do I want to risk double booking. 
It's frustrating paying for an upgraded feature when it doesn't have the functionality that I need. 
Can the resources be updated so that I can book 2 resources for one service? That would be amazing and I would stay with Square forever.
