Request for opening solution file outside working directory

Hello, I'm trying to open .sln outside source folder but it doesn't work. For example,
Working path: C:\src\proj\test.cs
Project path: C:\solution\test.sln
I tried to open one folder and added the other folder on vscode but it only searches a solution file in the root of source path. Can I open a source folder and load a solution file in different location?

Thanks
