Rename filenames in bulk

Hi,

I need to change a lot of existing filenames to filenames like this: articlenumber_1, articlenumber_2 etc.
The articles are now displayed like this:

serie1
104.98458-bumble-jt66-red_li-w_t1
104.98458-bumble-jt66-red_li-w_t2
104.98458-bumble-jt66-red_li-w_t3
104.98458-bumble-jt66-red_li-w_t4
104.98458-bumble-jt66-red_li-w_t5
104.98458-bumble-jt66-red_li-w_t6
104.98458-bumble-jt66-red_li-w_t7
104.98458-bumble-jt66-red_li-w_t8
serie 2
53.98809-bin_fuse-wb77-round_zi-m-t1
53.98809-bin_fuse-wb77-round_zi-m-t2
53.98809-bin_fuse-wb77-round_zi-m-t3
53.98809-bin_fuse-wb77-round_zi-m-t4
53.98809-bin_fuse-wb77-round_zi-m-t5
53.98809-bin_fuse-wb77-round_zi-m-t6
53.98809-bin_fuse-wb77-round_zi-m-t7
53.98809-bin_fuse-wb77-round_zi-m-t8
53.98809-bin_fuse-wb77-round_zi-m-t9


Needs to be:
first serie must be 12345_1 12345_2 12345_3 etc.
second serie must be 23456_1 23456_2 23456_3 etc.

how do i fix that? I've put all the files in 1 directory

If you can be bothered to look at the User Guide this will be blindingly obvious!
https://www.advancedrenamer.com/user_guide/metho d_replace

Replace: 104.98458-bumble-jt66-red_li-w_t
with: 12345_

and

Replace: 53.98809-bin_fuse-wb77-round_zi-m-t
with: 23456_

You can do this in a single step using two lines in a List replace method.
