can I define the spend authorization criteria based on expense type?

Summary:

Hi All

We want to define the spend authorization control based on expense type or template, however currently we find it can only be controlled based on BU.

Just wondering if there's any workaround on this?

Content (please ensure you mask any confidential information):

We get the request from our clients that for some specific expense types E.g. Travel and Hospitality, it's a MUST to have approved authorization before employee can submit the expense.

However for the rest E.g. Taxi fee, it makes no sense to use authorization.

The question is now we find the authorization behavior can only be controlled by BU level, which means if it's mandatory, this will apply to all the expense claim. This is not a flexible control and we are wondering if there's any workaround?
