how to restore data when one tape is missing from the backup set

We have the need to restore old data from a backup set that contains 5 tapes

Only one tape is present, the others are missing.

I want to restore the data that are located on the tape that i have

i have inserted the tape to the auto loader in order to Catalog and Inventory

Invetroy was done

i have selected the tape in the Storage menu, and press Catalog

it seems that BE tries to Catalog the entire set and not only the tape i have inserted,.

How can i force BE to Catalog only that specific tape, as i want to restore from that tape only. and the other tapes are not present

Thanks
