Disable the 'All' option in checkbox groups

[#1]

Description:
When you create a checkbox group in a custom form, an 'All' option is added when the form is displayed to your users.  There is no way (that I know of) to disable this option. It also doesn't appear in the form editor, so it was a surprise to see it on the published form.  There are cases where I don't want to encourage the user to select all options, and by putting 'All' first in the list, Workfront is making it look like that's what I want people to select.

You should give us the option to disable the 'All' option for checkbox groups. 

Why is this feature important to you:

The current implementation encourages users to select all available options, which is not what we want. We can get around this by making each item it's own checkbox, but this is very messy.  

How would you like the feature to work:

In the options for the 'checkbox group' field, have an option to 'Disable 'All' option'.

Current Behaviour:

'All' option is added at the top of all checkbox groups when custom forms are displayed to the user when making a new request.

This already exists. The field should be set up as a Single-select dropdown or Radio button rather than a Checkbox group.

Thanks @CelSal01! Unfortunately those other options all behave differently.  We want the user to be able to select more than one option, but also not encourage them to select 'All' by having that be the first option.  We also like the user experience of seeing all options displayed right away when viewing the form.

Single select dropdown only lets them select one option at a time:

Mutli-select dropdown dose let them select more than one, but also requires the user to click to see all options, and it still displays 'select all' as an option, which isn't ideal. It also cuts off the display of longer options:

Really I'd love a way to just disable the 'All' option in the Checkbox Group field type. That'd be great:
