An Interface to edit the selection in the existing mark

Hi All,

I have a problem wherein i have a mark with nodes as the entity. Now i need to make it interactive to allow user to edit(Remove or Add) nodes from the existing mark and therby create a new mark.

I Understand *Createmarkpanel as the only interactive way by which i can edit my selections in hypermesh. But *createmarkpanel only provides a panel to add entities to an empty mark.So no scope to edit the already existing mark.

Kindly suggest any other method to meet my requirement.

Thank you,

Regards,
