+==== The solution ====
+The solution was to pack all the elements into one string object, with each character reflecting the state of the respective process object.
+The idea is shown on the following gif image:
+{{ :2021-07-22_15-51-00.gif?direct |}}
+== The code which makes the trick ==
+<code lua>
+TRUE_SYMBOL =  '⚠'
+FALSE_SYMBOL = '-'
+NUMBER_OF_SPACES = 2
+function main (userId)
+   local bit_mask = R("demo_mask")
+   local t = {}
+   for b = 8, 1, -1 do
+        local symbol = hasbit(bit_mask, b) and TRUE_SYMBOL or FALSE_SYMBOL
+        table.insert(t, symbol)
+   end
+   local out = table.concat(t, string.rep(' ', NUMBER_OF_SPACES)) ; INFO("result_table: " .. out)
+   U("demo_string", out)
+end
+-- HELPERS --
+function bw(n)
+    return 2 ^ (n - 1)   -- returns weight of the bit in pos. n
+end
+function hasbit(x, b)
+  local p = bw(b)
+  return x % (p + p) >= p  -- returns if b is true/false; if hasbit(value, b) then ...
+end
+function U(reg, new_value)
+    local cur_value = R(reg)
+    if cur_value and new_value and (cur_value ~= new_value) then
+        WriteReg(reg, new_value)
+    end
+end
+</code>
+Using the font size and spacing adjusment in the lua script you can get necessary dimensions of this object.
