Mantis 1.1.6. Drop down list feature...

[swingkid]

Currently for fields like version number, you have to go to the manage views to add version numbers so that it will appear in the drop down list.
Is it possible or is there the capability for the drop down list be a drop down list and a text box so that if the listed version number is not there, then someone
could enter it in on the edit or new issue view instead of having to contact an Administrator to create it for him/her?
or maybe a version number like <new> be available so that a pop up in a new window could occur, they enter in the new version number, close the pop up and now the drop down list lists the new version number, instead of having to cancel or contact the Administrator to enter in a new version number.
