UserManager group and PPTP

hi
I setup pptp server with a default profile on Mikrotik RO 3.20 and UserManager.
I create an user with a Group name that defined in Mikrotik(ppp Profile) with rate limit and ip pool.When same user connects to pptp server he gets ip pool with no rate limit from default pptp server profile.
PLZ help me.

PPP does not support Group. HotSpot profile and user group are supported by MikroTik-Group (or User Manager group attribute).

thanks sergejs
Is there a way for group PPP users in User manager(ex:when i change a group attribute ,it effects group users) ?
Have you a suggestion?

As PPP does not support MikroTik-Group now, it is not possible to send such attribute, that specifies profile name.
