Incremental root-finding

[pzivich]

Is your feature request related to a problem? Please describe.

Solving for the roots of large stacks of estimating equations is difficult at times. Here one can usually break the stack into pieces and then solve each. I currently do this by hand for practical problems that involve lots of parameters. But that requires doing it manually

Describe the solution you'd like

A new optional argument that divides the root finding into separate tasks. This would automate what I implement by hand in these cases

Describe alternatives you've considered

Do by hand which can be tedious to do...

Additional context
