Not being able to add account object fields to rules loadable available fields.

Problem statement: Not being able to add account object fields to rules loadable available fields.

Reason: This required isCreateable permission on the fields.

Workaround: 
1)Grant "create permission" and move the fields over to available fields then remove the create permissions.

2)Share the list of fields that needs to be added to the Gainsight team, so we can add them through the backend(add these fields to the available fields).

Expectation: To come up with a long-term solution for the problem statement. i.e not to look for creatable permissions on fields while adding the fields to available fields.
