How do I manually (or better automatically) enter fiat deposit transactions into cointracker?

My only exchange is binance (UK not US) and I’ve recently deposited GBP into binance. However, cointrcker has not observed these transactions (since the net deposits field has remained constant) so I have tried to add these as manual transactions. This also is not going well. It appears that it is not possible to add a fiat deposit, only a deposit from another exchange or wallet?

Given how fundamental this feature is I’m guessing that this is user error, rather than a bug. Therefore could you please tell me how do I manually (or better automatically) enter fiat deposit transactions into cointracker?

Thanks in advance
