Second "#of beams" window for Storm Rain when used in dual setup (self-cast and with ballista totems)

Is your feature request related to a problem?

When two separate Storm Rain setups are present in a build, only one "# of overlapping beams" window is available. This generates incorrect DPS values, as the two skills have different damage calculations based on different supports, but they both use the same window.

Describe the solution you'd like

Enable a second window for the number of beams when a skill setup with a ballista totem + storm rain is present alongside self-cast storm rain.

Describe alternatives you've considered

An alternative workaround could be for the single window to count overlapping beams of all Storm Rain instances at once, but I don't see how it would correctly calculate DPS for those said instances.

Issue không nêu tên file hay test nào. Hãy bắt đầu bằng cách tìm cửa sổ "# of overlapping beams" hiện có của Storm Rain và phần xử lý cho các thiết lập self-cast và ballista-totem; hoàn thành nghĩa là hai thiết lập có thể sử dụng số lượng beam riêng biệt và tạo ra các giá trị DPS chính xác.
