[ingo] Maildrop to Sieve Fiters - Convert many users

[Me]

Hi. I am in the process of converting users on Horde 5 from using maildrop filters to sieve. 
I've set up the ingo sieve backend using the timsieved driver which connects to a dovecot managesieve instance. 
I was thrilled to see that I could just log into horde and save my filters again and they were automatically saved as sieve. 

I have several thousand users and I'm currently waiting for them to sign in and save their filters so I can then switch 
them to using dovecot for delivery. 

Is there a way to re-save a users mail filters from the cli so I can script it to update everyone? 
Or a way to force the filters to auto-save when the user logs into webmail?

Thank you.
