Adding a 'from' and 'to' date on valuation graph and plan metrics (adviser and client portals)

We have worked out/remembered how to zoom in on the dates on the valuation charts – however, it isn’t really possible to get it to select specific dates. Would it be possible to get 2 date boxes put in to allow filtering with a ‘from’ date and a ‘to’ date?

If this would be possible, would it then not make sense for the 3 boxes below the valuation chart to update to reflect the same time period, so clients can gauge performance over the period?
