Suggested Values

[Skip2MiLu]

Hi guys

Struggling to find documentation and threads that help me come to correct expression for what I want to achieve below

Below is my app and table structure.:

1. Exercise table:
   -has a list of exercises
2. Workouts List table:
   -List the workouts names
3. Workouts Plan table:
   -Links a set of exercises for the relevant Workout above.

Here are pictures of these tables to make easier to see how I have set them up

1. Exercise table:
   

   

2. Workouts List table:
   

   

3. Workouts Plan table:
   

   

So there is two things I want to achieve, of which for now I think I should just focus on point 2 below as point 1 might be a bit trickier to setup.

1. I want the User Favourite column to be a EnumList and I am still trying to figure out how I going to go about populating the rows in the column with user emails seperated by I delimiter upon select a action button and then it would also need a another action button to remove that user from the delimited list but still keep the other user email list that have also marked that exercise as favourite.
   For now I manually populating the User Favourite column and concentrating on point two below as this might be tricky to setup - as mentioned above.

2. So I want the list of exercises to be sorted alphabetically by exercises where the user’s email is listed for that exercise in question and the followed by the rest of the exercises that are not are not marked as user favourite.
   I am not sure if I should be using Valid if or Suggested values to achieve this?
   I initially thought that I should have a seperate Favourite Exercises that list exercises per user, but I do not want to show just user exercises. I want to show user exercises 1st for easier selection and then the rest of the exercises.
   

   

Any ideas on how to achieve this.
