I'm working on solidworks 2017, SP4.1 and trying the mirror drawing section for the first time.

I've created my LH part drawing, it includes one block callout for deburr ( which is not a symbol in SW for some reason)

Now, when I go to mirror this drawing, the symbol also gets mirrored,

I tried deleting the block and inserting a new one but every time I attach a block to a mirrored drawing, the block also gets mirrored.

Is there an option in setting where I can say don't mirror blocks? or would I need to make a mirrored block and have it reversed to the correct orientation when it  gets attached to a mirrored drawing.

Thanks,
