copy with line number

Sometimes I need to open a file modified by a colleague in the IDE. At this time, I need to copy the file name and locate the specified line. Most IDE software supports the format of "fileName.java:12" to specify the line number, so I hope to add a band The button for copying the line number. The desired position of the button is shown in the figure. You can bring the modified or newly added line number of the first line.
