Social Marketing: Adding field for text to share

Hi Everyone. Hope you are well today :smiley:

Could you give any advice on adding an additional input field for this plugin. I would like to have a field that allows for text to be added to the 'share'. For example, I will always want to encourage using the #todaysvisions. If I can add that to the 'share' then I have provided an auto reminder :smiley:

Thank you and have an awesome day
