After I asked I came up with same as you did.
:let @a=substitute(@a,'.*\zs ',';','')
Tested and it works.
Saves several steps editing in a register.
I am converting a spreadsheet with many tabs into a form to import into a database. The tabs have event names and dates, but that info is not in the each sheet. Each sheet is exported as a text file, the filename has the event name and date. The following will add that info to the beginning of each line of the exported sheets. Later all files will be concatenated and imported to a database. Tested individually, later in a function. ";" is being used as the field separator.
:g/^\d*;\+$/d " remove blank records
:v/^\d\+;/d " remove records without leading number and ;
:let @a=expand('%:t:r') " filename without path and extension
:let @a=substitute(@a,'\s*$','','') " remove any trailing whitespace
:let @a=substitute(@a,'.*\zs ',';','') " replace ' ' with ';' before date
:let @a=@a.";" " append ';' to filename;date
:g/^\d\+;/:normal "aP " prefix lines with filename;date;
