Consolidate inconsistent keywords in Photos on Mac

consolidate keywords in photos macos seqoia

I have many keywords that are inconsistent in spelling and capitalisation.

For example I have one keyword for 'sunset' and another for 'Sunset'

Is there an easy way to simply combine both of these similar keywords into one standardised key work.

My process for doing this now is to use the keyword manager rename the 'Sunset' to Sunsetaaa', then use a smart folder to add the keyword 'sunset' to to all those photos, and then delete the keyword 'Sunsetaaa'.

This process works but requires too many steps to repeat on all the keywords I want to change.

The ability to click on two keywords like we can click on two or more People and combine them would be ideal.

Is there an existing way to do this?
