FR: iOS Preset Save As... dialog : place existing name in text edit area

[Daniel Stenning]

It is common practice - in apps of all nature for a file Save As ... dialog - for the existing file name to be placed in the file name text editor area - because very often one wants to use this existing name. maybe making some small change to the name - suffixes etc.

Please add this small feature ti BIAS FX and BIAS AMP 2 iOS.
