Cannot reproduce seasons figures for various early seasons

Using the Historical data entry option I wish to add a player who played one match in a season. The add new entry option allows me to add his best bat and best bowling score as well as his season average for batting and bowling. All of these stats appear in his player page but matches played is zero. Is the only way to record matches played using Historical data by importing a csv file or am I missing something?

It would be extremely useful to be able to filter the current active players or if we can have a another option maybe "current Players" would be very helpful in avoiding having to use other software to display this seasonal information for frontend users.

I made a mistake when merging a player and have mistakenly merged a player together is there a way I can separate the players again? I have a division/grade thats split across 2 titles how can I go about having them under the one?
