Customise Voloview Express??

[hyposmurf]

This is possibly a mad idea,but is there any way of modifying Voloview Express,like maybe add some personalised macros or lisps?There is no command window so it looks unlikely,also the fact that its designed as a drawing viewer.I understand that you can make your own toolbars and also mark up the drawings with text and lines.Would be a great help if only a few basic commands were possible, such as move or erase.I have the annoying problem that I'll complete a drawing at home to then arrive in work and realise that 1 object is not postioned correctly etc. Does anybody know about any other ways in which you can customise Voloview Express?

There are a set modify command buttons in Voloview,but theyre greyed out,how do you get these buttons to work?Are they only available in a payed for version?
