Hi Dallas,
I think I have two options you can check that also.
first:
Create a two receivers, first for file then second for rfc and use "maintain order at run time in ICO" and second receiver for RFC and call RFC after placing the file.
2nd option:
create a two scenario(ICO's)
first scenario is for file with two receivers and
in second scenario poll the channel for second file and use it as a trigger for rfc
