Can you set the first frame's mask when use Sam3 object tracking?

First of all, great work!

According to the Sam3 object tracking doc, to track objects in a video:

1. set video
2. generate masks using text prompt
3. remove unwanted object by id
4. propagate

The problem is that the text prompt cannot segment the exact objects, so I want to use a different model to get the segmentations, so the steps can be:

1. get segmentation using other model
2. set video and the segmentions of the first frame
3. propagate

Basically just use the tracking ability of Sam3. Can this be done? Thanks in advance.

Good suggestion. I will see if I can add this functionality.
