Copy, paste, repeating, portal ?????

[newone]

I have a file of songs and a file where of dates and song that were used. I want to be able to create a new record in the file of dates and then search the file of songs and add ones to be used to the new record that contains the date.

I had thought of using a repeating field that I would click on and it would take me to a search screen where I would then have a pop up portal of songs to choose. The song chosen would be copied and pasted into the next blank repeating field. I could do as many or as few as I needed. This was working except I couldn't figure out how to get the copied data to go into the next blank repearting field. Well I suppose I could spend another day figuring it out but is there a way to accomplish these same feats with portals?

And also is it possible to have a scroll on you pop-up portal so that you could scroll through hundreds of records?

Thanks
