Hello,
In most pages, Main Representative is set us such that the text is blue, and if one clicks on it, it opens a new page with info of that person:
I would like to do the same for Parent Company:
I can’t figure out how it is done normally, for example with all those fields, where one can hold Ctrl + click to navigate to that page.
Does anyone have any tips? 
Using configurations, you can add a référence type field
BUT
The navigation functionality (zooming) of reference-type custom attributes allows navigation to the respective client pages but does not filter the corresponding record. This limitation exists due to a technical constraint in IFS Cloud.
This behavior is documented in the IFS Technical Documentation,
