CPanel shared hosting with multiple domains

I read the information on using CI4 with CPanel but I have a bit of an issue. I have several domains within my one CPanel, so my structure works as below

• /php
  
• /public_ftp
  
• /public_html
  
• /main-domain
  
• /ssl
  

but, then I have the following within the /public_html/ directory:

• /public_html/domain1
  
• /public_html/domain2
  
• /public_html/domain3
  

The very first domain I ever setup, has all the stuff for it within the /public_html/ folder, but it does have the folder outside the /public_html/ that is empty. This is not the domain I am looking to deploy to unfortunately. Is it possible to deploy to one of the domain directories inside the /public_html/ directory, because the only alternative I would have if this is not possible would be to get a second account and move that domain to that second account by itself, but that would incur additional hosting cost monthly, and I'm hoping to deploy multiple CI4 sites, but I can't afford to pay monthly hosting fees for each site I'm hoping to deploy. Any suggestions welcome because I have 14 or 15 websites I'd like to use CI4 to develop.
