Offline cache up-to-date logic problem, maybe just in my head

Hello,

we are using the RDM a few years now and it is running very smooth, also with 6.5k entries in one vault with a single SQL DB behind it. In the last weeks we migrated to the RDM DS and made a new structure with one vault per customer. This migration also was very straight forward and got us no real problem. Thanks for this :) But now I ran over a little problem. We are IT Consultants and have a very heavy need of the offline cache functionality, e.g. customer is offline and the technicians need to fix that. In our old structure this was not realy a big problem, because the offline cache was up to date as far the technician got online once a week. But now we have roughly somethin about a hundred vaults and we are facing the problem, that the technician gets the message that the vault is offline not accessible because it is too old. I can bypass the problem with RDM -> Administration -> System Settings -> Application Specific -> Cache/offline tab and set the expiration to 30 days and the notification to 14 days. The setting "Prompt refresh all vaults on startup" is not the real solution I am searching for, because it delays the start of the application with an unnecessary question and an "I open every vault and click on update" task. This is just my opinion :)
Could it be possible to implement a "hold all vaults up to date in the background when connected to datasource without opening every vault" function in the RDM? Or have I overseen this setting and me is just blind? :)

Thank you for your time

Best regards
