If there are multiple customers in a project, will reply to customer send a mail to all of them.

[Vipul Kulshrestha]

I have a project that has multiple customer role users.

When I try to tag any one of them individually using "Reply to customers" under comments, I do not see them while I do see the list of members of the service desk team.

If I choose the "Reply to customer" option, will all those who are added to the project as customers be notified and is there some way for me to tag a specific customer?

Currently I use the "Share" option with individual mail IDs but feel that is not really the intended way.
