Mapping labels between custom and coco dataset

[bowmount]

Hi ,
Is that possible to use the category id of the coco pretrained model on our custom dataset, for example,
if in Coco ds --> chair: 56, bed : 59,
then our custom ds--> bed :59, chair: 56, curtain : 81, lamp : 82... etc (so the added labels are started from the last classes+1 in coco label)
I am wondering if it can improve the fine tuning model performance because i have some similar labels with coco label in the custom dataset. Or do you have any suggestions?

Thank you
