User request: adjust game level 8, add level 9 for distributing a variable

[oliver-phet]

The game in equivalent expressions has a level 6 for combining like terms, level 7 for the distributive property, and level 8 for distribute then combine like terms. Level 8 though, jumps right into distributing a variable, and our students do learn x*x=x^2 until next year. Can you make a level 8 with just distributing integers then combining like terms, and make that where they are multiplying a variable times a variable a level 9? Thank you!!
