In the optional menu, there are three horizontal button icons on the far right of the "Open" and "Currency" lines.

Click enter to manage grouping. Add, modify, and delete groups as needed. Hold down the rightmost button of the group name, drag the group and reorder it. When you are finished, click Finish in the upper left corner, save, and don't call back directly.

Then in the optional menu, long press any fund, and the words Edit Grouping will appear. Click enter, check the grouping you want and confirm.

Now it seems impossible to operate in batches. In addition, on the website, there is no new grouping for the old version of self-selection, please note.
