I would like to remove the opus number from the field Title. The opus number can be 1 to 4 digits long and incentally followed by a letter.

How can I achieve this in an Action that removes "op." or ", op. plus the following digits (hence op.1, op.12a, op.123, op.1234 etcetera)

For example:
change "Shostakovich | String quartet no.8, op.110 ('Dresden') - I. Largo–"
to "Shostakovich | String quartet no.8 - I. Largo–"
