Is it possible for an assigned entry (via field type Entries field) to know what it has been assigned to? I have two entry types 'pipeline' (structure) and 'series' (channel). I know I can add children in a structure, but I want to keep 'pipeline' and 'series' separate to avoid duplication, as a series can belong to multiple pipelines.

I assign a series to a pipeline with a field type Entries field.

As an example I assign 'series1' to 'pipeline1' and 'pipeline2'.

What I'd like to know:

a) Is it possible for 'series1' to know it is assigned to 'pipeline1' and 'pipeline2'?

b) If it's not possible, is there a way to update the series entry when assigning to a pipeline?

Thanks for any help!
You could use the relatedTo param (docs).

{% set relatedPipelines = craft.entries()
    .section('pipeline')
    .relatedTo(yourSeriesEntry)
    .all() %}


Would return pipelines (if any) related to your series1.
