How to reduce position by different amount?

[mtomic-quant]

I have a Pandas DataFrame with Close, long_signal, short_signal, short_exits, long_exits columns.

I am trying to build Portfolio from signal by using:

pf = vbt.Portfolio.from_signals(
    close=df.Close
    entries=df.long_signal,
    short_entries=df.short_signal,
    exits=df.long_exits,
    short_exits=df.short_exits,
    init_cash=1000000,
    freq="1D",
    fees=0.000625,
    size_granularity=1,
    size=100,
    size_type="amount",
    accumulate=True,
    upon_opposite_entry="CloseReduce",
    allow_partial=False,
    )

My long_signal and short_signals columns are True and False and I allow accumulation so e.g. if two longs signals occur subsequently then I would just increase my position by a fixed 100. However my exits signals are integers and that means I should exit longs or short by more than. E.g. if my long_exit signal is 1 then I should reduce my position by 100, if its 2 I should reduce the position by 200.

How to incorporate this?
