Subs...Where do you locate this information?

Hi,
Just had a look at the new FM26 and the Pre-game Editor is more than l thought it would be. I enjoy making new data bases for games but this time l have pulled the 'Must Do Button' lol

Anyway l am struggling to find 1 thing...

Can anyone let me know where the information about substitutes is. I have looked all over the program but cant find that info anywhere.
Please help me before l pull what little hair l have left haha

Thanks in advance for your help guys oh and girls as now adays we can manage either gender based games GREAT STUFF!!

Thanks

Alan
