[Feature Request] Dash pattern matching MATCH without matching outputs

[ronw98]

Hi!
I want to use pattern matching to match an Input and a State to update a "global" output (with no MATCH wildcard), as shown in the decorator below
@app.app.callback( Output(utils.GRAPH_CREATION_DIALOG_GRAPH_TITLE, 'value'), [ Input({'type': utils.GRAPH_ITEM_EDIT_BUTTON, 'index': MATCH}, 'n_clicks') ], [ State({'type': utils.GRAPH_ITEM_SOURCE_DATA_STORE, 'index': MATCH}, 'data') ] )

Which is not yet possible is Dash. I found an easy workaround but it would be great if these kind of things could be available in the future!

Thanks!

This is inherently ambiguous and therefore will remain disallowed - see #1103 (comment)

Depending on what you're really trying to do, ALL may be the solution you're looking for. But this kind of question is better suited to https://community.plotly.com. Thanks!
