Multiple PLD option for a User

Hello Experts,

Can we give an option of having multiple PLDs to user to select the PLD from list, when it selects the PLD, it will opened.

One option is to choose the the PLD from Layout Designer windows, as we can make it default and then open it. I don't want to give right to user to make any PLD default ....

But I am looking for option as it ask me at run time when I press the Preview button.

Help Required...

Thanks
