Resources & Service Scheduling Issue

Hi all,

There are Sites/Equipments Resources for creating Service/Scheduling.

I have some problems while using this.

My questions is :

Can I use custom entities records as resource then only i will be able to use them in service and scheduling ?

Or how I can associate or schedule the resources with some cutom entity Record.?

For eg a cutom record of person using some service . ?

Please give some possible ways to do this !

Thanks
