hi everyone! I try to combine two pandas dataframe with different column lengths via vbt.combine func:
df1.vbt.combine(df2, combine_func=lambda x, y: x & y)
and got and error: Index at position 1 could not be aligned. Dataframes have the following shapes:
dt1 - (2976, 100). With two MultiIndex - rsi_window and rsi_crossed_above

dt2 - (2976, 10) With one index = ema_windows

I fixed it by increasing the dt2 columns to 100, but it leads to unnecessary calculation further. Is there any way I can improve it?
