RDM v 10.0.4.0 - Shared templates

I've create a group (type Workstation) and populate with subgroups (type workstation too) with multiple entries. All entries use $CUSTOM_COMPUTER_FIELDx$ to automate session creation. Then I save the group as shared template. When I add a new session from the shared template, all groups are deployed as "type group" and the $CUSTOM_COMPUTER_FIELDx$, all personalized icons are lost.
