Sorry if I cannot formulate clear, what I want, I am not native English speaker. I will try my best. 🙂
We register people in our free shop (we give free clothes for refugees) - with name and ID. Some people using different documents on different days.
We have a "registration" table with date, name and ID number (and many other things what is not important here). we have a "visitor" table with people, and "ID" table with the registered ID numbers. for every visitor there are some ID-s linked. I made a simplified version of this, to show what I want 🙂 https://airtable.com/shroibsb4V4JAcBXL If I fill in the registration table by name "Claudia" I would like to see by ID Claudia-ID-1 and Claudia-ID-2 to click on (or fill out a new one, if she comes with an other document)
Question: how is it possible by the registration, if we fill out the ID number, and someone was already in the system, we can choose from their linked ID numbers. now we have to fill out the ID number, what makes the whole process very slow.
