To standardize Titles I would like to move the key of a piece, however not to the end of the title. Is this possible ? If so how could I realise this in an Action? Actually, it is selecting a specific text, then move this text to a certain place

Examples
Change
'Trio for piano, violin and cello nr.1 in g minor, Hob.XV - I. Moderato'
to
'Trio for piano, violin and cello Hob.XV, no.1 in g minor - I. Moderato'

Change
'Waltz for piano in a minor, op.12/1'
to
'Waltz for piano op.12/1 in a minor'

Thanks in advance for any help

P.S. apologies for posting twice (an error occured) but don't see how I can remove second posting
