Request Conversations Reply-To/Support E-mail

Is it possible to use a single e-mail address as the reply-to address for requests?

i.e. When we reply to a request via SDP-MSP the e-mail message has a reply-to address that is the support e-mail address that is associated with the Account for that request. Trouble is, we then need an alias for each and every account as the support e-mail address must be unique for each account.

we have about 200 accounts and climbing so needless to say the aliases become a problem. If we could configure requests to all have a reply-to address that matches the e-mail address configured in the mail server settings then our problem would be solved.

is this possible or is there a better way to ensure that conversations are maintained?

thanks,
