Merge ACF fields in new one

Hi,

I try to merge (fusion) two Advanced Custom Fields (meta) into one.
The goal is to creat all in one field.
Something like this…

I would like to see : [FIELD 1 Title] – [FIELD 2 Date] [FIELD 3 description] with only one field call.
to use it facebook description.

Thank you 🙂
