Offline mode for building Workspace dashboards

In Report Builder, it's possible to turn off data updates (Offline mode) so a user can more quickly build out a report with dummy data first, then just run a full data update at the end.

However, in Workspace the user is required to wait for data to update after almost every edit.

Would it be possible to add an "offline" function to Workspace to roughly replicate the existing behavior in Report Builder?
