Hello,
No, currently there's no option to display contact that are not linked with recent events.
One way to go about it is to create SalesOpportunities for possible deals and keeping the followup date updated. Then you could easily see the records that weren't updated in a while and take action.
The other way is creating a custom module that would gather customers contacts and filter out those that have some recent action. Unfortunately, currently we don't have plans to add such feature to EPESI.
Kind regards,
Arek
