Search and Replace should allow a single line to be replaced by multiple lines (to easily add or append more actions to functions and subroutines that repeat that single line throughout the script). Example:
Replace:
Setvar "[this]" "[that]"
With:
Setvar "[this]" "[that]"
Setvar "[andthis]" "[andthat]"
Setvar "[morethis]" "[morethat]"
