REST API Status Change

I am designing a REST API.

I have a single resource that I want to be able to change the status of for different conditions e.g. the URI is:

Applications/{application_id}/

The possible status changes are to set the application to:

1. Cancelled
2. SignedOff
3. Hold

Each status change will require different information e.g. a reason for cancelled, a date for signedoff.

What would be a good looking URI to handle this? I had thought of

1. POST: Applications/{application_id}/Cancel
2. POST: Applications/{application_id}/SignOff
3. POST: Applications/{application_id}/Hold

but it doesnt seem right to me.

EDIT:

I should have mentioned that I was already planningPOST: Applications/{application_id}to update an existing application with a full set of application data.
