Crosscheck additional markets with specific lot size / different risk sizes.

Please allow lot size to be modified for each symbol under the crosscheck additional markets at least in case of fixed lots. In order to have unbiased portfolio KPI in the case of fixed lots, we need to adjust lotsizes for each symbol.

Although it would be also interesting to allow different risk sizing for % of account or fixed $$ etc. for additional market symbols in cases where we wish to create a bias on purpose (or equalize some other unintentional bias) towards one or more symbols in the portfolio kpi.
