[TYPO3-templavoila] Hide standardtemplate for editors

[Chris Bernhard]

Hi @ all,

after mapping a site template with templa voila
i have a new site template in the site creating wizard.
But the standardtemplate is still visible for editors.

Is there an way to hide this one for the editors?
I appended a screenshot for this issue. I want to hide
the "Standardvorlage" (the left one with the question mark icon)

Many thanks in advantage,

Chris Bernhard
