Input Dialogue - PopUp

In an input dialogue, I have 4 prompts that each uses the pop-up menu option. I need the item number for each. If I save this item number, is it possible to have the popup menu already on this item number the next time I open the input dialogue. I'm thinking something similar to

PopupMenu MyList mode=2


It's a bit annoying to have to reselect everything from the start each time I need the function.
In case you refer to the DoPrompt command, it should be sufficient to set the corresponding variable to the 'default' value (variable, string, or index), see
