Currently we can’t permanently connect a point in a image excerpt to another point in a image excerpt by pencilkit tool. Because rearranging of nodes causes displacement of handwriting.
Therefore binding of handwriting to two or multiple nodes would be very useful for many users. (Specially for studying extremely detailed Anatomy diagrams)
Thank you for writing in. I have raised your request to our Development team but we cannot assure a time frame when it will be put into effect. Please feel free to contact us again if you need any assistance and we will be happy to provide further help.
