New Version of Adobe Sign vs Old Version

Dear 
Adobe sign provided new interface for your very good application. However, the old interface was also available for user sole decision.
Recently I have realised that this option "old interface" is not longer available.

Based on that i was forced to use the new interface and i found something that, for my point of view, is a downgrade on the app.

For meetings with more than 10 attendees, i used to use excel to collect emails and names. Once those were there (in excel) i used to open the old interface of Adobe sign, and making a kind of copy and paste (in once) of more that 10 representative emails directly to the adobe sign. Sucessfully used to be the process for more the 3 years.

Now with the new interface, i need to copy and past every single email to the correspond field. More than that, i need to client "add" to open a new field for new copy and past of representative email.

Something that used to spent 2 seconds, now became, more than 5 minutos. Terrible.

in another words, i have not seen where the new interface is better of previsous (old) one.

In this way, i kindly requests adobe to make available the option (use the old interface) again for user decision.
