Selecting values for creating Source´s accounts

Hello devs, I would like to know how to allow selecting different values for an attribute when creating an account on a Source. For example, I want to implement a dropdown menu (or a similar component) to choose between roles 1, 10, or 100. Not the hardcoded value of 1 as it is. The same should apply to Perfiles = Profiles. Thank you!

SailPoint ISC doesn’t have that feature for the custom values apart from SailPoint’s predefined types like Generator and Identity Attributes.
