Configuring different SQLEXEC options in replicat depending on source operation

I'm extracting INSERT/UPDATE/DELETE operations for a table, and on the target database, I want to run a different stored procedure depending on whether the original transaction was an INSERT or DELETE (and not run any stored procedures upon UPDATE). Is there a way to do this? Any hints/guidance would be appreciated. 

I've been trying to use the FILTER argument, but don't actually have a filter expression to apply, so the below doesn't work:

 MAP my_table,TARGET my_table,

FILTER(ON INSERT),
SQLEXEC (ID proc1, SPNAME insert_procedure_name,
AFTERFILTER,ERROR RAISE, TRACE ALL)
;
MAP my_table,TARGET my_table,
