OG Professional/Data Entry - Default Expressions for Data Entry

Hi all, 

I am trying show default sieve sizes on the PSD - Data table within OG Data Entry, so that data entry staff do not have to enter sieve sizes. I noticed on the OG wikipedia the following page: https://communities.bentley.com/products/geotechnical1/w/openground-wiki/53849/are-there-any-example-default-value-expressions-for-data-entry

Are there any other default expressions available? What is the full list? This link only shows count(), max, and if statements. Right now I think I can tackle the above problem by making many nested if statements that count the number of rows and print a sieve size based on the row number. This is still not ideal as I would like to just have all the rows already displayed, when the data is input into PSD General (the controller group/grid). Is there an elegant solution for this? 

----Edit----

As mentioned by Martyn below, there is no elegant solution for this. While writing the default expression, I noticed that the default expression has a limited character count. For example when trying to copy the following expression in, it gets cut off at about 'No. 40'. This means even the inelegant solution is incomplete

if(count()=0,'3"','')+

if(count()=1,'2"','')+

if(count()=2,'1.5"','')+

if(count()=3,'1"','')+

if(count()=4,'3/4"','')+

if(count()=5,'3/8"','')+

if(count()=6,'No. 4','')+

if(count()=7,'No. 10','')+

if(count()=8,'No. 20','')+

if(count()=9,'No. 40','')+

if(count()=10,'No. 60','')+

if(count()=11,'No. 100','')+

if(count()=12,'No. 140','')+

if(count()=13,'No. 200','')
