Hi,
1. If you’re using a dropdown list you should be able to change the “Any” text in the field settings. In the form editor, next to the dropdown where you’ve chosen the field type (e.g. “Dropdown”) there should be a cog icon, click this and you should be able to change the “Blank prompt” (e.g. the text to show when nothing is selected.
See this gif if the above doesn’t make sense:
2. This is not straight forward to achieve and would require custom coding. If this is urgent I am available for hire to look into this for you. If not, I’ve added this requirement to the todo list and will release it in a future version of the plugin.
Hope that helps,
Don
