You can use a singleton java bean to store the state of that sequence
and then in the file route use that in a file filter to only pickup
the correct file.

You can implement a custom file filter, using the filter option, where
you can then access that singleton bean to get that sequence number.
The other route can then also call that singleton bean where it can
update the sequence.
