combine ARS & manual selection for lambda z in bear [🇷 for BE/BA]

Hi yjlee168,

So, I mean that when I choose 'manual selection' for lambda z estimate (step 3), I can manually select the data points based on previously generated '***_lambda_z_select_all.csv' (ARS method), but only for six points, although for some subjects '***_lambda_z_select_all.csv' contains more than six points.

Anyway, thanks again to you and Helmut!
