Calling explictly a previous dump

Hi,
I hope you are doing great.
Let's assume I have a dump called mydump, that prints the system state every 40 steps.
Later my system evolves and stops if a given condition happens (I use an if inside the run command). Many times this stop happens at some intermediate step, not multiple of 40, so the last system state is not dumped with mydump.
Can I call the dump command explicitly inside the if? right now I am just copying the full dump inside the if and using a write_dump, but this duplicates a lot of instructions than are difficult to keep in sync .
Thanks in advance
