Orderby usersetting

[Diogenes_ASBL_V]

Hi

I have a table, of which I would like to arrange the rows according to the first letter of the column [Name].
Now I want the user to be able to select which letter the list starts with:
for example: in user settings the user indicates that he wants to start the list with D -> the list would then start with all the names starting with D, then E,… then Z, A -> C

Do you think it’s possible?
