Slash command bar limited for bots

I own a server on Discord and my server has Discord bots too. While my server isn't particularly large in terms of members, there are still a significant number of bots on the server to entertain my community and have fun with the bots.
With the introduction of the slash commands, it was also decided to no longer support bots with other prefixes in the long term. The problem isn't that slash commands have been introduced - this was a good idea to unify the control of the bots.

The problem is the limitation of bots in the slash command bar. I, as the owner, only have a limited number of bot slots that can use slash commands. And this is an extremely big problem. As I explained earlier, in order to keep my community entertained, I have a lot of bots. Much more than the slash command bar currently accommodates. And I NEED these bots! A waiver is NOT POSSIBLE!

Due to the limited space in the command bar, I can no longer use some bots because there is a limit.

Let's say the slash command bar can only hold 20 bots and I have a total of 40 bots on the server, then I CANNOT USE 50% of the bots!

The only reason I can't use these remaining bots is because they also use slash commands and there's no place for them in the slash command bar.

Now, a possible solution might be to swap the bots that use slash commands for similar bots that still use the old prefixes with letters and characters like *, !, +, $, etc., if any are still available would be found - but they aren't! Due to the fact that Discord no longer wants to support them, it is impossible to find other bots because all bot developers are forced to switch to slash commands.

I ask for a solution! - Best of all, an expansion of the slots in the command bar!

Thanks!
