Is there a simple way to combine 2 photo albums in my iphone?

Hi All,

I only have my iPhone (no lap or desk top) and have realised I have multiple albums of similar (or the same) photos.

I.E. albums are ‘Renovations’ and ‘Unit Renos’ and I really only need 1 album with all the photos from both albums together in it.

Is there an easy way to combine these similar albums on my phone?

Or do I have to basically start again from scratch by removing all photos from 1 album back to “All Photos”, deleting the album and then go back into “All Photos” to find them again and add them to the other Album?

Thanks In Advance!
