Load Application command

Hi,

I use a third party software called Questica to AutoCAD Add-In that I use to import a BOM from the Questica database to insert into an AutoCAD drawing. I recently installed DraftSight Professional and was able to install the icon buttons (the .cui files) and tell DraftSight where to look for the files. The third part of the setup is to use the LOAD APPLICATION command and to activate Questica.dvb. Problem is DraftSight only see's three types of files for LOAD APPLICATION. They are .lsp, .mnl and .dll

Is there anyway to load a .dvb file or to convert the .dvb file to something DraftSight can use?
