Automate other field entries depending on one table reference field

Hi, I'm looking for a way to display table references for the same customer but automate the entry on one click over multiple fields.

I know I can do multiple values in "show as" functions for a Client reference field, however I don't like how it looks and also it's less readable on the mobile app which is how this particular form will be used.

Basically I would like to find a way to make two tables act as follows.

One table is called "customer information" one table is "Mobile delivery"

I would like the first few fields in "Mobile delivery" to fill in after selecting the customer's name in the first field

so first field "Client name" is a reference field, once filled the next few fields like phone number, email and location become unhidden and automatically fill in based on the customer entry in the other table.
