I don't know about your software but I can highlight, for example, the first design by left clicking one time and then go over 5 designs or so and put my cursor on that design, hold down my shift key and left click again. This highlights all 5 designs. Then follow your usual steps. Hope this works for your software too. You've probably already tried this, but just in case.
I have tried to do this,but have to open each design separately, on the viewing page , to be able to convert. Is there a way to select multiple designs & convert without opening them? I have PE Design which allows me to do this , but I can't convert VIP files.
I have only been able to convert one at a time also, but I would love to be able to convert multiples also maybe then I wouldn't be so behind all the time....hope we get a good answer....thanks for asking.
