Option to create folders

Is your feature request related to a problem? Please describe.
when the number of diagrams increases it becomes very difficult to locate the diagram you are looking for.

Describe the solution you'd like
When creating multiple diagrams it would help to have a folder structure and have the diagrams placed in a chronological order.

Describe alternatives you've considered
Following a naming convention would help but ultimately it cannot replace grouping and bucketing into a folder .

Additional context
None.
