[Koha] Matching rules on record import

[Cab Vinton]

Am I correct in assuming that Koha can only use one matchpoint at a time?

We've recently completed an inventory of our collection and we ended
up with several different indentifiers for our items: ISBNs, LCCNs, &
OCLC numbers.

It would be nice if during the import process Koha could check a
sequence of matchpoints when checking for duplicate holdings (e.g.,
first check ISBN, then LCCN, etc.) This is currently not possible,
however, right?

Thank you,
