Ability to run MFD in Vizzy designer(?)

yeah the title isn't that great so let me explain
basically, in SR2 today, if you want to test your MFD program, you have to save to craft, launch, test, if something goes wrong, go back to the designer and edit the MFD program.
this method of testing MFD programs is extremely time consuming and inefficient.

what I'm suggesting is, if you had the code on one side of the screen and an MFD screen on the other side (the size of the MFD screen would be the equivalent of whatever you made it in the designer) and a "Run MFD Program" button or something like that, it would make testing things a lot easier and more efficient.
