Edit abherrant KH readings

Is it possible to remove a single abherrant data reading from the chart log so that in chart display (in GHL Connect) the scale isnt automatically spread out to accomadate it? Its just that occasionally when doing maintenance, say changing a reagent bottle or recalibrating sensor etc the first readings afterwarwards are often way out before it settles again. It also might be useful with other chart sensor readings? Alternatively adjust the scale of the display log so single readings are not accommodated. I ask this in order to see relatively the minor daily swings in the readings(data-points) otherwise these major swings overwhelm the chart scale
