Is it possible to remove organization from ticket if the summary contains some specific word?

[Anssi]

Our customers use JSD as it should used. A customer belongs only one organization and by default, email tickets are shared to all his colleagues when he sends email. 

We have some cases when our customer sends email to our JSD from other email service and the email contains information (like attachment) which should be processed securely and not to be shared to any other than reporter and possible requested participants?

Are there a way for example to use automation which removes the organization from this particular ticket?

 I just tested and Organization is not an available field under the edit issue automation in JSD.

However, I did see that if you set your rule up so that this issue goes through a Transition that you have coded to postfunction empty the organization field, you could empty it out:

This seems to solve my problem. But I don't find that "Clear Field Value" -post function from our version; -server JIRA version 7.6.1 and JSD 3.9.1 . Does it need some plugin or what?

Hm, this is available in cloud, but not server that I can see.

However, we have JIRA Suite Utilities add on which includes this postfunction.
