Is there a way to set COMBINED disk quotas?

My current pricing scale is primarily based on combined storage quotas no matter which service is using them.
Basically, what they use for mail, is no longer available for web and vice versa. Is there away to do this with ISPConfig? Thanks.

 

That's somewhat disappointing. I hope this can be accommodated in a future version.
Many thanks for your prompt response.

 

That will be great then. I would've upvoted it, but need an account. Thanks for pointing that out.
