In card layout, there is a parameter called link in which you can use these links as per your requirement a!documentDownloadLink(), a!dynamicLink(), a!newsEntryLink(), a!processTaskLink(), a!recordLink(), a!reportLink(), a!safeLink(), a!startProcessLink(), a!submitLink(), a!userRecordLink(), or a!authorizationLink().
Convert this thread to a feature request? It makes sense to include optional link to button so button components can perform all the actions links can.
