DIY ETFs and self made portfolios

Salams. Has anyone made their own stocks portfolio-a mixture of islamic index funds and shares theyve verified to be shariah compliant so they have their own ETfs? And can these be done through an ISA? And do online platforms such as AJ Bell or vanguard allow you to do such a mixture?

Don’t see the point of creating one for yourself if there are already shariah complaint ETFs out there unless you are trying to achieve something specific. History has shown that passive index funds give better returns than active funds on a long run.
