Keep the cursor position after filter out some unwanted lines

[azter222]

I am lucky to be able to find this nice plugin.
Especially, the function for filter out unwanted line, like

• :K <wanted string>
• :Rej <unwanted string>
• :'<,'>Rej <- filter selected lines

I usually filter and repeatedly use the above 3 method to remove the noise.
And, each filter operation will obtain a qf-window as subset of previous one.
Intuitively, noise should be emitted from the top to down.
Therefore, the top of newer qf-window is no need to check again.
Unfortunately, the cursor position will jump back to first line when filter out noisy.

Is that possible to keep cursor position to nearest top line, if not exist, choose the nearest button line?
