(User Macro) How to feed data into velocity template parameter

Question

Is there a way to push data into a velocity template parameter of type enum?

example...I would like to have a drop down with all the confluence user groups listed in the parameter selection screen (user macro edit mode)

## get all user groups
   #set ($_allGroups = $userAccessor.getGroupsAsList())
  #set ($_grpNames = "")

#if ($_allGroups)
         #foreach ($_group in $_allGroups)

#set ($_grpNames = "$_grpNames,$_group.getName")

#end

## this does not work...( type=enum|enumValues=$_grpNames )

## @param _group:title=Groups|type=enum|enumValues=$_grpNames|required=true|desc=The LDAP group name to perform search for members in, if no group is provided, default is all users.

Thanks for clarifying. I've been looking for this answer the last 2 hours.

User macro parameters are just velocity comments that Confluence interprets and creates Velocity variables from. So, nope it's not possible ... it would be nice if they beefed up the variable types a bit (attachments, users, groups, etc.).
