5.5 Warlock Accessing 5.0 Invocations in Character Builder?

Will D&DBeyond ever implement backwards compatibility for 5.5 Warlock to use 5.0 Warlock invocations? I saw a post from 2024 asking this and based on my research, I didn't find an answer. Has WOTC discussed this yet? If so please direct me where to go. 

I have been playing in a campaign for almost 4 years now. We started with 5.0 characters and upgraded to 5.5 characters. We are heard WOTC advertise backwards compatibility meaning my new 5.5 warlock can use any 5.0 invocations that weren't reprinted like Eldritch Sight. So far I cannot choose that as an option in the character builder. My temporary solution was to give myself the Eldritch Adept feat and choose the old 5.0 Eldritch Sight invocation, and now it works. In the character builder, I just left open an invocation slot to account for this. I just took my 15th level in Warlock and want to use Shroud of Shadow. I cannot do the same trick because the character builder only lets me add an extra feat once of each type- so I can't choose Eldritch Adept again. 

Would like WotC to create a backwards compatible Homebrew for all the Stuff the builder cannot do by default so we can add them to our characters in the builder.
