Option for more holding incoming recource

[FritzHugo3]

Please give us an option in factories and other builds for more than the 2*recipe.
maybe as a global gameoption instad 2,3,4,5 * recipe
or maybe as a table for set recipe 2,3,4,5 * recipe
or in every factory set free the number to hold incoming recources as fix number (like manual insert) or 2,3,4,5 * recipe

E.g. Yelow factory with 4*speed 3 upgrades, you cant fill it enoth fast with multiple arms. (but they are many more reasons for this suggestions.)
