Views send module for emails: Remember these values for the next time a mass mail is sent. (The values are not stored per user.)

Hi Drupalers, 

I´ve got the following problem: 
I am using the “Views Send”-module to send emails. The module works fine, but the problem I am facing is that I have various users on my website: When you send an email with this module, there is the option: “Remember these values for the next time a mass mail is sent. (The values are not stored per user.)” If you tick this option, then the text for the email is saved for the next time you send an email, but as it already says in the description: “The values are not stored per user” and I need exactly this functionality! Do you have any ideas on how to solve this problem??

My only idea how to solve this problem would be:
Make a subdomain for each user (as I won´t have that many users on my website, it would be possible, but still it is a bit of pain in the ass and rather my last option). 

This question here, that unfortunately is unanswered, would also solve my problem: http://drupalanswerscm.blogspot.com.br/2015/03/how-to-save-more-than-one…

Hope someone has an idea how to fix this problem 🙂

Thank you very much in advance!
