Save data manually　

[Background]
I’m using ContactForm7 to let users submit specific data and save them by Flamingo plugins. In some cases, a user inputs data instead of other persons. It is inconvenience to fill form several times, so I would like to set another form which can input data for several persons at once.

(ex.)
current form: name1, birthday1 (data for one person)
another form: name1, birthday1, name2, birthday2 (data for a few persons)

[Problem]
I can set another form by ContactForm7 but in that case the datas between two forms mentioned above are different and can not be listed same in Flamingo admin.

[Question]
Is there any way to save each datas in same data format ?

(ex.)
input: name1, birthday1, name2, birthday2
=> save as below
1. name:name1, birthday:birthday1
2. name:name2, birthday:birthday2
