Hubspot SEO Coding Improvements

Our Hubspot blog has a few SEO issues around the pagination mechanism that we use: [login to view URL] We're looking for someone with great experience using Hubspot CMS, with a bit of SEO know-how as well as a solid foundation of coding. We would like for someone to fix the following issues for us: 1) Missing Canonicals on Blog Listing Pages, Author Pages & Tag Pages Hubspot either allows us to make all pages after 1 canonical to page 1 (meaning Google's crawler only sees the posts in page 1) OR no canonical usage at all. Since we want Google' crawlers to see all of our blog posts, we need to add a unique canonical tag to every page: -Blog listing pages -Author pages -Tag pages You can see the effect of this from a crawler ran in Moz Pro (attached XLS and PDF... note that the XLS is more detailed about this particular issue and the PDF is more high level + describes all the Issue Types) The below page suggests adding a dynamic canonical to the header of the blog listing page so that it adopts the page URL, allowing Google to identify it as a unique page with a confirmed canonical.

Some say it can't be done, others say there's a hacky way of doing it through Google Tag Manager? Others say it can be done with HubL and a URL mapping tool. This developer request suggests the HubL and URL mapping tool, though doesn't go into details on "how": [login to view URL] This Q&A is related, though they're talking about Archive, the fundamentals are the same: [login to view URL] They specifically link to this Moz page: [login to view URL] Please shoot over a few links to other Hubspot sites you've built or worked on, as well as a best-guess time estimate to complete this work. Thanks!
