Can i simulate behaviour of aspose 16.0 in aspose 23.0 when inserting document

It seems Aspose 16.0 used to create copy of each style with colliding name except to styles related to TOC.

I used ImportFormatOptions.ForceCopyStyles and it created copies of all styles.
But the behaviour for TOC styles is not the same as it was in aspose 16.0.
I think aspose used to owerwrite these styles from source into destination but i am not sure.
Thanks.
