If you need them to be physically modelled then yeah, you will have to just place them yourself.
The Timber framing addon will do it for you, but it takes alot of configuration (from what i remember, havnt used it since v.2014) to get it to work correctly (still alot quicker than placing all the studwork 1 by 1.
This may be something you could do using Dynamo however i have not looked into it. Check out dynamobim.com forum and search if anyone has accomplished this.
Another method may be to create a "Generic model line based" family, with an array of your stud work family, which when loaded into your project you can pick or draw around your walls, set the size, offset and spacing of your studs etc. This option may not work as i havent tried it and it is more towards the advanced side of Revit family creation, but this link will provide a intor kind of guide to creating something like this: https://www.youtube.com/watch?v=lJik85qaVsY
