How to only show my part of split bill in trends tab

I use the split bill feature a lot to split joint expenses with my partner. However, the full amount appears under spending in the trends tab making it hard to track my personal spending. Is there a way to only show my personal expenses in the spending summary i.e. just the part of the split allocated to me?

One workaround I’ve found is to split each joint expense into 2 categories, with one category excluded from the spending summary. The issue with this approach is that it involves splitting each transaction twice, once for split bill and again for split category. Given the split has already been done for the bill can this automatically exclude the bit that isn’t mine from the spending summary?
