Serena Dimensions: open Files with correct Filename

At work we use Serena Dimensions for Version Control.
Double-clicking a sourcefile opens the code in the editor of your choice, but unfortunately Dimensions doesn't provide a meaningful filename as the clicked element is downloaded to a temporary file and the editor shows just the name of the temporary file.

After requesting an improvement in the Dimensions community i got some great hints from Paul Caruana and finally implemented the following workaround:

• Create a batch file

  echo off 
  set dimexe="c:\program files (x86)\serena\dimensions 12.2\cm\prog\dmcli"
  set ueexe="c:\program files (x86)\ultraedit\uedit32"
  set fi=%2
  set fi=%fi:"=%
  set ver=%3
  set ver=%ver:"=%
  set typ=%5
  set typ=%typ:"=%
  set tmpfile=C:\tmp\%fi%.%ver%.%typ%
  
  echo parms: %* 
  echo file: %fi% 
  %dimexe% FI %1 /USER_FILENAME="%tmpfile%" /EXPAND /OVERWRITE 
  %ueexe% %tmpfile%
  

• Create a new "Tool" inside Dimensions:
•  Menu "Tools" -> ""Customize Menu and Toolbar"; Tab "Tools" -> Create a new Tool (Star-Button), choose a name (e.g. "MyEdit").
  Configuration: 
• Command: C:\foo\projects\cmedit\cmedit.cmd
• Arguments: $[Specification] $[Filename] $[Revision] $(Product):$(Workset) $[type]
• Start In: c:\foo

This gives me a "MyEdit" Entry in the Context Menu which downloads the file & launches Ultraedit with a meaningful filename - Mission accomplished!
