/*
In this section of the script you'll see that we have four roles calles SEO, DEV, PPC, and PM.
Change these to match the names of the roles that you've assigned inside your projects.

For Example, Let’s change the role from SEO to OUTREACH:

OLD CODE

let seoVal = "SEO",
          indexSEO = data.roles.findIndex((item, i) => {
            if (item.name != null) {
              return item.name === seoVal && item.users.length
            } else {
              return 0
            }
          })

     let seo =' ',dev = ' ', ppc =' ', pm = ' ', catId = ' '

NEW CODE

let outreachVal = "OUTREACH",
          indexOutreach = data.roles.findIndex((item, i) => {
            if (item.name != null) {
              return item.name === outreachVal && item.users.length
            } else {
              return 0
            }
          })

     let outreach =' ',dev = ' ', ppc =' ', pm = ' ', catId = ' '

*Adding new Roles*

For each role below you'll see a code block like:

let seoVal = "SEO",
          indexSEO = data.roles.findIndex((item, i) => {
            if (item.name != null) {
              return item.name === seoVal && item.users.length
            } else {
              return 0
            }
          })

To add a new Role, prepend the above codeblock above line 92, and update the variable name,
and the indexSEO and "SEO" role name to match your new role.
