Extract deeply nested (more than 1 level) plan

[mnunezdm]

Is your feature request related to a problem? Please describe.

Extracting data with the sfdx force:data:tree:export only allows to extract one level of nested elements. I think it would be great to extract deeply nested plans like for example: Account->Case->Task

I managed to manually extract the data in two steps, manually edit the data plan, and insert them using the sfdx force:data:tree:import -p

Describe the solution you'd like

Ability to, for example, retrieve a list of queries and make the plan automatically for example:

$ sfdx force:data:tree:export -p -q "SELECT Id, Name (SELECT Origin FROM Cases) FROM Account"
                                    "SELECT Id, (SELECT Id FROM Tasks), (SELECT Id FROM Events) FROM Case"

Describe alternatives you've considered

NA

Additional context

This is the workaround I did: https://salesforce.stackexchange.com/questions/240042/sfdx-forcedatatreeexport-beyond-1-level-deep/255711#255711

Yep! Same problem :) we need 5 level deep

[sfscgjohnson]

Agree this is needed.

Having the same issue here. Would be awesome to have up to 5 level :). Also taking into consideration that the query could reference the same object more than 2 time like contact -> contact -> contact or something similar would be great
