Change prompt when adding new group / new loop

Hi to all.

not a big deal I think but would be really great for end user. ![Screenshot_2019-05-24-09-24-45|300x500]

1. What is the general goal of the feature?
The only Goal is to change the message/question show when a user enter in a loop.

Add new group ?
Add a new group foo bar

I would like to be able to short and clear that question :slight_smile:

Add a new foo bar

2. What are some example use cases for this feature?
We create and use forms with many loop :

  • session
    • observer(s)
    • geopint(s)
      • species
        • media

At each screen, collect ask the user if he want to add a new group. It is quite a lot confusing and not so easy.

3. What can you contribute to making this feature a reality?

In the past, @pailletm did it in a collect version (2017)
