Putting files (images in particular) in a 'custom' order

[Chris G]

I seem to have this problem regularly but still haven't found a good solution.

I currently use Digikam but the problem applies equally to other
applications, I haven't found anything that does what I want.

I want to select pictures randomly from various places (i.e. from
various different Digikam albums) and place them in a new album in a
specific order which has nothing to do with their dates, alphanumeric
file name or anything of that sort (no pun intended!).

*Surely* people want to be able to do this.  Currently in my case it's
simply because I have taken two sets of photographs of the same trip,
one lot in one direction and the other lot in the opposite direction.
I want to collate a set of pictures of the trip in 'geographic' order
from the best images selected from the two albums.  I can't find any
way of doing this apart from laboriously renaming each image as I
select it and even then if I change my mind and want to add one in the middle
somewhere I've got a horrible re-ordering problem again.
