### Description
The recently-added **acc_json** module does not support the _multi_leg_info_ parameter from the main **acc** module.
### Expected behavior
**acc_json** module could add the extra leg info attributes in the JSON data, as the **acc_radius** module already does. Behavior could be the same for the JSON module.
Maybe @jchavanton can assert if it is feasible or not...
Sure, I will have a look when I have a chance. Very soon hopefully.
tested a bit more and double check the logic used in acc.c
Closed #1745.
@jklingenmeyer please test and confirm this is what you needed
@jchavanton many thanks for your quick addition. Behavior is the one I meant. Sorry for my late feedback.
